The motors of the GM series are characterized by particularly precise concentricity and show a flexible performance spectrum that predestines them for applications that require a wide range of requirements.
They are particularly reliable and, in the IP 54 version, popular in the pharmaceutical industry.



Solid line = continuous operation
At an ambient temperature of 25 ° C, the maximum anchor temperature is reached under permanent load.
Dashed line = repeatable work area (S-3)
This area can be used under different load characteristics. It is limited by the influence of temperature, commutation and demagnetization.
Dashed two-dot line = short-term operation
The motor may be loaded briefly and repeatedly. If this range is exceeded, the motor will be irreversibly damaged.
Tolerances according to VDE 0530. For values ​​not specified according to VDE 0530, a tolerance of +/- 10% applies.
If the drive shaft is fitted with a shaft seal, a slightly lower torque is to be expected due to friction losses. The technical data given in the table and the performance curves relate to a DC voltage supply with a permissible harmonic content of up to 5%. The data are only valid for use in an ambient temperature of 0 ° C to 40 ° C. This range must neither be exceeded nor fallen below, otherwise there is a risk of permanent magnetic weakening.

Accessories and add-on components for engines

Gearbox: Planetary gearboxes of the PLE series are available for all motors. An assignment and a detailed description of the gearbox to the individual motor types can be found here …
Brakes: The brakes are permanent magnet-excited holding brakes. The supply voltage for the brakes is 24 V. The respective holding torques are assigned to the motors.
Power is supplied via a separate connection line (special versions on request).
Encoder: Two different encoder types are optionally available:
Type 1: 2-channel encoder with a pulse number of 500 or 1000 pulses / rev
Type 2: 6-channel encoder with 500 or 1000 pulses / rev, each with a 5 V signal.
Tachos: DC tacho generators with a voltage constant of 10V are used as tachos. Detailed technical data on request.
Cover hood: A suitable cover hood is available to protect the 2nd shaft end.
DC servo controller: An assignment of the controller to the motor types and a description of the controller can be found in the section Servo controller.
